||The reason is the deliveries of new COS TDSTAB references and TDSTAB rmap.
||The ACS team has determined that the IDCTAB o911150jj_idc.fits is faulty. Images that use this file cannot be aligned with other images. Conversation with Jennifer Mack confirms that this file is faulty. This issue can be fixed by instead using s5d1409dj_idc.fits.
||Standard delivery of ACS WFC superbias, superdark, and sink pixel reference files following the anneal on September 20, 2018. These files will be used to calibrate ACS WFC observations taken between September 20, 2018 and October 5, 2018. Delivered by Tyler Desjardins for ACS.
||New weekly biases and darks were created for the new anneal month and need to be delivered for GO observations. These files are available for STIS CCD observations taken after 1 Sept. 2018 Delivered by Allyssa Riley for STIS.
